- As a part of the Low Flow Stacked Rapid Sand Filtration team, I have contributed to the ongoing construction of a new, 12" diameter filter that will be used to model such LFSRSFs currently being built in India. I have gathered a materials list of parts necessary for this construction, and I have helped create a simplified, accessible design for the filter hydraulics, and formalized design constraints for the filter through myriad head loss calculations. I helped pioneer a new way of joining filter components using gaskets, stainless steel shim stock, and hose clamps, and applied this method in the construction . I have helped order and machine several of the parts which will shortly be used in construction. of a filter column, entrance tank, and exit tank. I led efforts to replace filter inlet and exit piping with flexible PVC, and created a construction method to insert couplings and barbed-to-male adapters through filter column walls. I began construction of the backwash pipe and investigated the uniformity of flow distribution through inlet piping via the flow ratio. I created various schematic diagrams and documented design motivations and procedures that will be helpful when the construction of this filter is eventually replicated.
